WASHING-MACHINE TUB.

Specification of Letters Patent. Patented Aug. 2, 1921.

Application filed April 22, 1921. Serial N0. 463,532.

T 0' all w [tom it may concern Be it known that I, VnRNon B. EDwAnDs, a citizen of the United States, and a residentof Middletown, county of Henry, and State of Indiana, have invented a certain new and useful ashing-Machine Tub; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to washing machines containing a movably mounted tub, which tub is adapted to contain articles to be washed and the liquid for washing the same.

The chief obj set of the invention is to construct a tub in such a manner that said tub when rocked or oscillated within the frame of the machine will agitate both the washing liquid and the articles to be washed in such a manner that the cleansing action of the former upon the latter will be facilitated in an improved manner.

The chief feature of the invention consists in providing the washing machine tub with oppositely inclined corrugated means in the base thereof, and associating therewith suitable deflecting means to cooperate with the corrugations.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is a perspective view of a washing machine including the improved washing machine tub. Fig. 2 is a central cross sectional view of the washing machine tub.

In the drawings, 10 indicates a washing machine frame of suitable size, material and character. 11 indicates means for suitably supporting the washing machine tub 12. Herein such support is indicated as a pivot, and the tub is adapted to be rocked upon said pivot by suitable means, herein illustrated as a manual means, such as the handle 13. All of the aforesaid is old in the art.

The invention is clearly illustrated in Fi g. 2 wherein the washing machine tub is shown in cross section. Said tub is substantially or approximately elliptical in outline, and the upper portion thereof is apertured to receive the cover or closure member 14. Suitable flange means 15 forms the walls of the a erture in the top, and said flange means receives the closure member and securely supports the same to close the tub. The flange means is extended upwardly and outwardly to form a. deflecting portion 16 of arcuate form, which arcuate deflecting portion merges with the elliptical wall. The deflecting plates or portions 16, therefore, are oppositely positioned and are herein illustrated as positioned equidistant from the center of the elliptical washing tub.

Half of the tub is substantially similar to the other half, and, therefore, a description of one-half will suffice for an understanding of the other half. The lower or bottom half portion of the tub is provided with a plurality of superposed downwardly inclined ledges 17, the successive ledges being connected by side walls 18. The last or lowermost ledge 17 discharges into a pocket portion 18 which is provided with transversely inclined portions which are adapted to drain the water in the tab to the lowest point thereof. A suitable drain-cock 19 is positioned at substantially the lowermost point of the tub, and thus, is adapted to drain the tub.

It will be understood,therefore, thatabove each of the series of inclined ledges upon each side of the median plane through the tub is positioned the deflecting plate 16. Each deflecting plate 16 is adapted to cooperate with the opposite series of ledges or corrugations, so that in the rocking movement of the tub, as a whole, the articles to be washed and the washing liquid will be thrown by the corrugations or ledges from one side of the tub to the opposite side and will be deflected downwardly by the deflecting plate 16, whereupon the corrugations beneath said deflecting plate receive said articles and liquid and project the same against the other deflecting plate 16, which thereupon deflects said articles and liquid upon the opposite corrugations. Thus, the liquid and the articles to be washed execute a deformed figure eight movementor a movement which may be well. represented by the outline of a pretzel.

The invention claimed is:

1. A washing machine tub comprising a body portion having a plurality of downwardly inclined ledges separated from each other by downwardly extending wall portions, the lowermost ledge being positioned adjacent the lowermost portion of the tub,

body portion having a plurality of down wardly inclined ledges separated from each other by downwardlyextending wall portions, the lowermost ledge being positioned adjacent the lowermost portion of the tub,

whereby said tub will completely drain the 10 water to the lowermost portion thereof when stationary and Valve means for draining said tub and positioned in the lowermost portion thereof.

In witness whereof, I have hereunto af- 15 fixed my signature.
